CHARLES E. GURRIE, OF BUTTE, MONTANA TERRITORY.

CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 316,879, dated April 28, 1885.

' Application filed December 27, 1884. (No model.)

To aZZ whom, it may concern.-

Be it known that I, CnARLEs E. (JURRIE, a subject of the Crown of Great Britain, who have declared myintention of becoming a citizen of the United States, residing at Butte, in the county of Silver Bow, Montana Territory, have invented certain new and useful Improvements in Oar-Brakes, of which the following is a description.

This invention relates to that class of carbrakes which are used by hand to check the speed of railway-cars; and it has for its object to provide means whereby the hand-shaft may be automatically locked at any point to which the operator may strain, it means whereby the said shaft may be released by the operators foot with case at any time desired, and means whereby the locking device is protected from dust and dirt, thereby insuring its working at all times and preventing it from grinding-wear.

To this end my invention consists in the construction and combination of parts forming a car-brake, hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my invention. Fig. 2 is a longitudinal vertical section. Fig. 3 is a plan View of the same, and Fig. 4 is a detail view of the disk inverted.

A represents a portion of the platform of a car. B represents the hand-wheel, and C the hand-shaft on which it is fixed. The chainshaft is journaled vertically in the platform, and extends below it to receive and Wind up the brake-chain D.

E is a disk fixed upon the shaft (J, and provided with a downward-projecting rim, F, within which is a circle of ratchet teeth, G.

H is a detent fitted to slide vertically to engage the teeth G, to hold the disk against the turning strain of the brake'chain. The detent is provided with a stud, I, around which is a spring which continually lifts uponthe detent to throw it into engagement with the teeth. The detent is also provided with another stud, J, projecting up through the base K, and provided with a pedal, L, upon which the foot of the operator may press to disengage the detent from the teeth G of the disk. The base K is to be secured to the platform of the car, and it serves to support the detent and spring, and is itself kept in a fixed relation to the disk and teeth by bearin g upon the shaft 0. The rim of the disk projecting down around the teeth and the teeth facing downward, prevents any possibility of dust accumulating in the teeth. The pedal also flares out over and to all sides of the hole through which stud J rises, thereby preventing dust from entering the device at this point, thus insuring its constant readiness for use, so that CHARLES E.
